The CyScan optical receiver is divided into three vertical channels:
Lower, Middle
and
Upper
. The proportion of beam signal being received in each channel is used to determine
the correct angle to set the optics.
If one of the reflections in the list is selected, its elevation relative to the horizontal is shown
by the position of the yellow target symbol on the right-hand side of the Leveller Graphic.
The blue line represents the laser beam, and this moves as the
+/-
buttons are clicked.
When the laser line points to the centre of the target symbol, this indicates that the leveller
angle is ideal for the selected target
Scanner tilted up and pointing at a target mounted higher than the sensor.
To change the scanner tilt mode and leveller angle
Note:
The Dashboard needs to be in command mode to make any changes.
1. Click on the
+/-
buttons to adjust the angle. The adjacent list of estimated elevation
angles for visible targets helps you to arrive at the best leveller angle.
2. Click on the
Apply
button to confirm your changes.

Manually Tilting the Scanner
The
Manual
mode is used to tilt the scanner optics to a user-defined angle so that the
centre of the fanned beam is pointing at the target. This may be necessary when the
CyScan Vessel is close to a platform and the targets are positioned above the sensor.

Spirit Level
The Spirit Level indicator, on the left hand side of the Tilt
pane, displays the roll and pitch of the vessel as measured
by the Vertical Reference Unit within CyScan. The graphical
display represents the roll and pitch angles in the same
manner as a bullseye spirit level. The current values are
displayed in text at the bottom of the control. A ship outline
is shown in the background to indicate orientation relative
to the vessel.
